All the fun of the fair

There may trouble ahead (specifically an 'utterly terrifying' 'hulking great mountain of pain') but, according to my newsreader, there will also be a 2.2% increase in fun and frolics in the shape of railway-based fairs. It doesn't say whether the rides, candy floss and hot dogs will  be confined to station concourses, or whether there will be actual in-train entertainment. I suspect it's the former, on the grounds that it's hard enough finding space for a normal-sized piece of luggage on a Virgin Pendolino, let alone a coconut shy.
